Mirror support assembly for heliostat and heliostat

Abstract

The invention discloses a reflector support assembly for a heliostat and the heliostat comprising the reflector support assembly. The reflector support assembly is used for connecting a reflector anda mirror bracket; and the reflector support assembly comprises an adhesive upper body, an adhesive lower body, a sliding bearing, a connecting rod, an adjusting body, a buffer body and a positioning body, wherein the adhesive upper body is fixedly connected with the reflector of the heliostat, and the adhesive lower body is fixedly connected with the mirror bracket of the heliostat. The reflectorsupport assembly for the heliostat provided by the invention can reduce the stress borne by the reflector under the action of great wind resistance, so as to prevent the reflector from being damaged due to bearing large stress, and the reflector support assembly can ensure that the surface type of the reflector is kept the same as the initial horizontal state under various elevation tracking working conditions, so the reflection efficiency of the reflector is improved.

Description

technical field [0001] The invention belongs to the field of solar thermal power generation, and in particular relates to a reflector support assembly for a heliostat and a heliostat comprising the reflector support assembly. Background technique [0002] As a clean renewable energy source, solar energy is being used more and more, especially photothermal power generation technology is an emerging solar energy utilization technology after photovoltaic power generation technology. Among them, tower-type solar thermal power generation technology has energy storage, peak regulation benefits have received widespread attention. [0003] The function of the heliostat in the tower solar thermal power generation is to gather sunlight to the heat absorber, and generate high-temperature and high-pressure steam by heating the working fluid, and then drive the steam turbine to generate electricity. The heliostat is a concentrating device composed of a reflector, a mirror frame, a track...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the supporting components of the reflector are all elastic members, which can reduce the stress on the reflector under the action of wind resistance while supporting the reflector, so as to prevent the reflector from being damaged due to large stress. When the reflector is in a horizontal state When the reflector support assembly is under the positive pressure of the reflector, it cooperates with the mirror frame to make the reflector present a suitable surface shape. The magnitude and direction of the pressure on the mirror support components are constantly changing, and limited by the lack of rigidity, resulting in a large change in the surface shape of the mirror, which has a great impact on the quality of the light spot of the heliostat horizontal angle tracking
